Description
Technical field
The present invention relates to the high accurate device for filling of powder of the weight precision of fast, each filling powder of a kind of process velocity and placement method.
Background technology
Tradition powder filling mechanism, adopts and is referred to as weighing instrument, to powder accurate weighing, then carry out filling.This mentality of designing, procedure of processing can be caused various: first need constantly within claiming, to add a small amount of powder, until the powder in claiming just has reached or just over predetermined weight (weight exceeded must in acceptable error limit), then by claim in powder filling in packing container, then carry out compacting, finally encapsulate.
Because whole course of processing procedure of processing is various, therefore be difficult to promote work efficiency, again because the speed of manufacturing line is determined by that link the slowest on manufacturing line, therefore the process velocity of above-mentioned powder filling mechanism cannot improve, and will cause that the production efficiency of whole production line is low, productive costs is high, cannot meet the demand of large-scale industrial production.
In order to solve the problem, the patent No. is 201520020458.3, what name was called " high-precision powder filling mechanism " patent discloses a kind of technical scheme, high-precision powder filling mechanism in the program adopts servomotor to keep the powder pressure to discharge nozzle outlet by screw rod, the powder density at this place can be consistent preferably, and feed rods carries out scraper to the powder that discharge nozzle exports, the high powder of weight precision can be scraped fast.
Difficulty due to powder filling is that the filling amount that needed by packing container and filling accuracy determine jointly, if filling amount is very large, also easily realize even if filling accuracy is very high, such as filling amount is 1000 kilograms, filling accuracy is ± 0.1%, the magnitude of error allowed also has 1 kilogram, if and filling amount is 10 grams, filling accuracy is ± 1% magnitude of error 0.1 gram allowed, therefore for the filling amount very little (the filling amount of less than 30 grams or 30 grams is called filling on a small quantity herein) that packing container needs, filling accuracy needs to reach ± the powder filling of more than 5%, realize large-scale industrial production.If adopt title to measure, then production efficiency is difficult to improve, and adopts screw rod and servomotor to carry out the method for metering filling, is difficult to again obtain enough filling accuracies.
Above-mentioned patent is due to the shared large hopper of multiple filling apparatus, in hopper, the amount of powder constantly changes, the powder of discharge nozzle is fallen into from hopper outlet, its pressure be subject to is in continuous change, when the powder in hopper is a lot of, pressure is large, and when the powder in hopper is little, pressure is little, and its density can along with change in pressure, the large then density of pressure is large, and the little then density of pressure is little.Because metering mechanism's (feed rods) is close to discharge nozzle, although the amplitude therefore falling into the powder variable density of discharge nozzle is less, for the high-precision powder of needs (such as high-grade coffee powder) is filling, greatly can affect filling accuracy, and powder also will through follow-up charging conduit, system for compacting etc., these all can produce error, finally affect filling accuracy.Through experiment, said structure is used for the coffee powder of filling top grade, 9 grams of its filling accuracies of coffee powder (weight franchise) can only reach at most ± and 5%, this makes above-mentioned filling mechanism cannot be applicable to need the powder of high precision (namely filling accuracy is greater than or equal to ± 2%) (such as high-grade coffee powder) filling.
Applicant finds, such scheme is to feeding machanism, the i.e. structural development of extrusion screw rod, large not to the help of filling accuracy, cannot offset cause the powder falling into discharge nozzle from hopper outlet to be subject to due to powder change in hopper pressure change and the factor such as follow-up charging conduit, system for compacting to the harmful effect of filling accuracy, cause filling accuracy to be difficult to raising.
